Europe PMC has added protein and chemical structures from Protein Data Bank (PDB) and ChEBI via the BioEntities tab.
There are some amazing examples in this paper, which was a collaboration between scientists in America, the Netherlands and UK:
'Supersite of immune vulnerability on the glycosylated face of HIV-1 envelope glycoprotein gp120'
The paper investigates susceptible target regions on specific HIV-1 envelope glycoproteins, and the abillity to now view protein and chemical structures really helps to visalise this research.
To have a look for yourself click on the BioEntities tab for the paper, scroll to 'protein structures', 'data citations' or 'chemicals' and then click on ‘View Structure’ link.
It's especially enlightening (and fun!) to rotate and zoom the PDB structures.
Let us know how you get on - as always we're happy to receive feedback so that we can make improvements.
